Which of the following fields cannot be used to store area code data?

1. Phone

2. Email

3. Text

4. Multi Picklist

The correct answer is: Email

Email fields are specifically designed to store email addresses and are not suitable for storing area code data. The format and validation rules for email fields expect the input to be a valid email address, which consists of characters and structure distinct from numeric data like area codes. In contrast, the other field types—Phone, Text, and Multi Picklist—are all capable of handling area code data. The Phone field is explicitly intended for storing phone numbers, including area codes, while the Text field can be used to store any alphanumeric strings, thus making it suitable for storing area codes. Multi Picklist fields allow for selection of multiple values, which could include area codes if set up that way. Therefore, the only choice that does not fit for storing area code data is the Email field.
